Totally different - Anonymous is more of a romance. Deja Vu is one of the 'sisterhood' novels. The sisterhood is a group of dissimilar ladies who have been 'hurt' in different ways who have banded together to creatively get justice for each other and for others. I'd go with the sisterhood. They do frustrate the men in their lives, but the romantic relationships aren't the main part of the story - so you might want Mr. & Miss Anonymous.
